LTC3423 Datasheet - Linear

LTC3423, 3MHz Micropower Synchronous Boost Converter

U U LTC3423/LTC3424

Features

* s 1.5V to 5.5V Adjustable Output Voltage s Synchronous Rectification: Up to 95% Efficiency s 1A Switch Current (LTC3423) or 2A Switch Current (LTC3424) s Fixed Frequency Operation Up to 3MHz s Wide Input Range: 0.5V to 5.5V (Operating) s Very Low Quiescent Current: 38µA (Burst Mode® Operation) s No

Applications

* requiring less than 0.75W of output power and the LTC3424 for 1.5W or less.
Switching frequencies up to 3MHz are programmed with an external timing resistor and the oscillator can be synchronized to an external clock.
Quiescent current is only 38µA in Burst Mode operation, maximizing battery life in
